摘　　要：可靠性问题是系统设计、研究和运行过程中必须考虑的关键因素之一。采用冗余技术是提高系统可靠性的重要途径,文献[1,2]以此作了高度评价,系统可靠性冗余最优问题已引起了广泛的重视和研究,形成了一些有特色的算法,文献[3,4]中作了综述,但在以往的研究中。The optimization problem for system reliability with redundancy is essentially nonlinear integer programmins. Many methods have been proposed for solving this kind of problems. However, most of them are only suitable for series-parallel systems and single objective problems. This paper presents a criterion of optimal redundancy, and then formulates a heuristic alsorithm for multiple objective problems of reliability optimization. This algorithm can solve multiple resource objective optimization subject to nonlinear constraints and also can be applied to any complex system, where the structure need not be series. The effectiveness of the algorithm is shown through two examples.
